    Abstract: A COATING INCLUDES AN ANTENNA UNIFORMLY DISTRIBUTED AND DISSOLVED IN BOTH A MATRIX AND A LEUCO-DYE PHASE OF THE COATING. THE ANTENNA READILY ABSORBS ENERGY, WHICH MAY BE APPLIED IN PARTICULAR PATTERNS TO THE IMAGING MATERIALS. THIS ABSORBED ENERGY HEATS THE MIXTURE, WHICH CAUSES THE LEUCO-DYE AND THE ACTIVATOR TO MIX AND REACT, CAUSING THE LEUCO-DYE TO CHANGE COLOR, THUS PRODUCING A MARK. A METHOD FOR PREPARING AN IMAGING MATERIAL INCLUDES PROVIDING A POWDER HAVING AN ACTIVATOR AND AN ANTENNA, DISSOLVING THE ACTIVATOR/ANTENNA POWDER TO FORM AN ACTIVATOR/MATRIX PRE-POLYMER SOLUTION, PROVIDING A LEUCO-DYE ALLOY, AND DISPERSING THE LEUCO-DYE ALLOY INTO THE ACTIVATOR/MATRIX PRE-POLYMER SOLUTION TO FORM A RADIATION-CURABLE PASTE. AN IMAGE-RECORDING MEDIUM INCLUDES A MATRIX HAVING AN ANTENNA AND AN ACTIVATOR, AND AN ALLOY DISPERSED IN THE MATRIX AS AN INDEPENDENT PHASE. THE ALLOY INCLUDES AN ANTENNA, A LEUCO-DYE, AND AN ACCELERATOR.

    Abstract: This invention relates to a direct, multi-color imaging composition, comprising a radiation absorber (antenna), a color former mixture of at least two color formers, and one or more activators, wherein one of the color formers reacts at a first elevated temperature to create a first color and another of the color formers reacts at a second elevated temperature to create a second color that is distinct from the first color.

    Abstract: A substrate (114) has a first dye layer (118) that locationally changes in color to a first color upon exposure to an optical beam at a first power level, and a second dye layer (120) that locationally changes in color to a second color upon exposure to the optical beam at the second power level. The optical beam impinges a region of the substrate to render the region with a color selected from at least one of the first color and the second color. The optical beam impinges the region at a power level selected from at least the first power level and the second power level (608).

    Abstract translation: 衬底（114）具有第一染料层（118）和第二染料层（120），所述第一染料层（118）在暴露于第一功率水平的光束时在位置上颜色变为第一颜色，所述第二染料层（120） 当以第二功率水平暴露于光束时的颜色。 光束撞击基板的区域以使区域具有从第一颜色和第二颜色中的至少一个中选择的颜色。 光束以至少从第一功率电平和第二功率电平中选择的功率电平撞击该区域（608）。
